Hola List - this just in (see informative dense collection zone  nomenclature 
policy message below).  It would seem the Meteoritical Society  has stepped 
up to the plate and now the meteoritemen will be separated from the  
meteoritekids (with one possible exception of the latter - the grandfathered  
"meteoritekid" fellow listmember).  I bet purchases from LeSoukville are  NOT included 
without some sort of affidavit regarding coordinates referenced to  an 
unadulterated geodesic datum.  Glad we'll be seeing a meteorite  coordinate shower, 
soon:)  Saludos, Doug

Dear all,

This message is to inform you that the Nomenclature  Committee has 
once again made changes to the Guidelines for Meteorite  
Nomenclature.  We have now agreed to a rule under which meteorites  
from dense collection areas can be formally paired at the time of  
initial characterization, and thereby be subject to relaxed  type-
specimen requirements.

Under this rule, meteorites from dense  collection area may be 
declared by the Committee to be paired if there is  overwhelming 
evidence, including geographic data, supporting the  claim.  When the 
Committee votes to accept such evidence, each new  specimen will still 
get a separate name, in keeping with current  practices.  However, the 
requirement that 20 g or 20% of the total  mass, whichever is less, be 
deposited in institutions that have well-curated  meteorite 
collections will apply to the pairing group as a whole instead of  to 
individual specimens.

The Committee will only consider requests to  pair newly discovered 
meteorites with each other or with other formally  named meteorites.  
Requests to pair existing, formally named meteorites  in the absence 
of new specimens will not be considered.

All pairing  groups approved by the Committee will be announced in the 
Meteoritical  Bulletin.  

The revised Guidelines for Meteorite Nomenclature are  online at
http://meteoriticalsociety.org/bulletin/nc-guidelines.htm

I  apologize to those of you getting this message more than once...
there is  significant overlap of the mailing lists I have to use.
